You could also call these "Third-person 3D Action Games", but then you'd be getting into rather close proximity with stuff like Gears of War/Bullet Witch and the like, and even the GTAs/Crackdowns/etc. -- which do have their own, unique labels (Third-person Shooting and Free-roaming Action respectively), but the beat 'em up label is far more unambiguous (and, by the way, just as weapons fighters like Samurai Spirits are still called simply fighting games, so too "hack and slashers" like DMC and Ninja Gaiden are still called beat 'em ups, like God Hand or Bayonetta). But if you have a better name for them by all means let's talk about it here.
So. The DmC demo is up now (at least on Live -- no idea about PSN), and I'll be downloading and playing it in a sec. I generally don't play demos but I am really intrigued by this and I haven't played a brawler in ages, so I'll bend my rules for this one. In the meantime, I thought I'd give you my provisional ranking of all the modern 3D beat 'em ups I've so far played.
1. Ninja Gaiden
2. Devil May Cry
3. Genma Onimusha
4. Onimusha
5. Bayonetta (based on the first two missions only)
6. Otogi (based on playing up to the last stage, or what I think was the last stage)
7. Berserk: Millennium Falcon Hen Wasurebana no Shou
8. Ninja Gaiden 2 (based on playing up to the first boss)
9. Devil May Cry 2 (based on playing up to that tank fight that occurs early on)
10. Devil May Cry 3
11. The Bouncer
Those are all I can think off the top of my head for the moment. If you post other titles below I'll place them on the ranking if I've played them. And like I said, don't hit the roof please when you see DMC2 higher than 3, but that's the impression that I got from 2 after playing it for like an hour or so back when it first came out. All these games will eventually be finished and reviewed, so like I said: the ranking is provisional.
Also, it could be argued that the Onimushas have quite a bit of "adventuring" in them, so they don't belong on the list, but that would make DMC borderline unacceptable too, since it has a little bit of adventuring itself (though of course a bit less than the Onimushas). Personally, I enjoyed the COMBAT in Onimusha, and especially Genma Onimusha, far more than in DMC3, which if I remember correctly has almost no adventuring element, so on the basis of this view I believe it and games like it should be on the list. But of course I draw the line at Biohazard and even Dino Crisis, which have almost absolutely nothing in common with the genre.
Games I haven't played at all but plan to: Devil May Cry 4, Ninja Gaiden 3, Ninja Blade, Otogi: Hyakki Toubatsu Emaki, God Hand, Onimusha 2, 3 and Shin, Berserk: Millennium Falcon Hen Seima Senki no Shou, Madworld, Max Anarchy, El Shaddai: Ascension of the Metatron, and possibly some of the God of Wars, but probably only after I've played most of the others.
As a side note, I might also try Ninja Theory's Heavenly Sword and Enslaved: Odyssey to the West (the latter of which is on its way to me right now in my latest Amazon order), but I don't expect to play very far into them. Still, it might be interesting to see how far they've come along with DmC, so giving these games at least a try is a must.
